The applet below creates problems for you to practice deriving the sum of products forms of arbitrary Boolean expressions. You will be given a Boolean expression in three variables, and asked to solve for its sum of products form. When you have computed your answer, enter it using the "a", "b", "c", "+" and "'" buttons and then click on the "Check Answer" button to find out if you did the problem correctly. If you wish to correct a mistake, push the "Start Over" button. The "Next Problem" button will generate another expression for you to work with.

Do you need some reminders about
